T 0 all to/remit may concern:

Be it known that I, SANDOR Oszn, citizen of'Hungary," and resident of Martins Creek, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Mechanism for Ascension and Descension, of which the following is a specification.

This invention relates to mechanism for ascending and "descending relatively to a supporting point, and is especially applicable to construction scaffolds and balloons within the limits of the mechanism.

The object of this invention is the provision of a mechanism which may readily be carried by the work-scaffold or balloon has ering thereof.

ket and which is operable therefrom for the purpose of ascending and descending for comparatively short vertical distances.

A further object of this invention is to keep the balloon basket or scaffold on which it is used level during the'graising and low- The landing of a balloon has heretofore been accomplished usually with the aid of persons on the ground because of the difiiculty of accurate management of the balloon vertically. By means of my invention it is possibleto make safe landings from balloons without outside help.

My mechanism can also be used to advantage. in connection with captive war observation balloons. In cases .where the hawser of the captive balloon breaks, it has been necessary for the observer to leave the basket or carriage and escape by means of a parachute; the balloon and basket containing valuable instruments and maps often being lost by being blown over the enemies lines. I By means of my invention, the observer can lower himself to the ground, thereby saving not only his life, but the maps, instruments and the balloon itself.

The use of my invention on work scaffolds provides a-safe and rapid means for raising and lowering the same controllable from within the scaffold, which is .kept level durin the raising and lowering operations.

Tor the attainment of the aforesaid objects and advantages, I employ the mechanism shown in its preferred form in the accompanying drawings, in which;

Figure 1 shows an elevation of my improved mechanism, as it appears, when attached to a balloon basket.

Fig. 2 is an isometric drawing of that part of my mechanism-which is attached to the basket or carriage and Fig. 3 is a side elevation of the same.

In the practical embodiment ofmyinventron, the hanger or supporting bracket 1, has mounted therein pulley 2, said han er being shown at Fig. 1 supported or hung y the usual balloon ropes 13 from balloon ,1 though it is obvious that the hanger 1 may be supported in any desired manner, as, fro the roof of a building.

A balloon basket, scaffold or carriage 8 is supported from hanger 1 by means of a suitable wire or rope cable 8, which passes over pulley 2 and around pulley Said pulley 5 is mounted on shaft 14 which is supported in bearings 6, which are in turn mounted on one end of said carnage 8. The other end of sald carriage carries bearings 7 which support shaft 'l6, said shaft carrying drum through belt 10. Said motor may be sup-..

porte plied by a storage battery not shown.

When it is desired to make a landing from a balloon (Fig. 1) current is supplied to motor 11 to rotate it in the proper direction to unwind cable 3 from drum 4. Said cable is thereby loosened, the weight of the carria e being sufficient to take up the slack as it evelops, thereby gradually lowering the carriage. The entire operation is readily controllable at will from the operators position in the carriage, which finally reaches a lower position as shown by the dotted lines in Fig. l.

To raise the carriage, the motor is rotated in the opposite direction, wherebycable 3 is wound around drum 4 and shortened, thereby raising the carriage toward hanger 1. If said carriage is used as scaffold, and the hanger'l is supported from the roof or side of a building, the raising and lowerby a bracket as 9 andcurrent suping of the carriage is accomplished in the same manner.

It is obvious that said carriage will remaln level during the raising and lowering is drawnin and paid outon both sides of pulley 2 during said operations.

The various operating parts such as the motor and pulley are so proportioned as to operations since the same amount of cable 1 Jf'reyent the weight of the carriage and its contents from causing the drum to unwind when motor 1s not running.

Ilia-t I-cla1m 1s:

mechanism of the character described, a carnage, a cable for supporting said carriage, and means carried by said I calgle"passing-around said pulley and back 2. mechanism of the character de-' .scrilied, mcarriage, a hanger from which said carriage is supported, a pulley mounted in said. hanger, a pulley mounted at one end of said carriage, a drum mounted at the other end of said carriage, a cable attached to said drum and passing around both ofsaid pulleys and means for rotating said drum for winding and unwinding portions of said cablewhereby said carriage is raised and lowered relatively to said hanger. j

3. In a mechanism of the character described, a carriage, a hanger, from which said carriage. is supported, a pulley mounted in said hanger, a pulle mounted at one end of said carriage, a cab e attached to said drum and passing around said drum and both of said pulleys,and means for rotating said drum for winding and unwinding equal portions of said cable on each side of said hanger pulley whereby the level position of said carriage is maintained, while said carriage is raised or lowered.
